TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 292,896, dated February 5, 1884.

Application filed September 14, 1881;. (No model.)

I0 all whom, it may concern:

Be it known that I, Fnnnnrcx COLEMAN, of Ilion, in thecountyof Herkimer and State of N ew York, have invented certain Improvements in Two-Wheeled Vehicles, of which the following is a specification.-

My invention relates to that class of twowheeled vehicles commonly designated roadcarts or village-carts; and the improvements consist in a novel arrangement of the springs, whereby the unpleasant horse-ma tion is prevented, the primary feature of the invention consisting in attaching the side springs to the axle by hinge-joints.

In the accompanying drawings, Figure 1 represents a perspective view of a vehicle einbodying my improvements; Fig. 2, a side elevation of the same, with the wheels removed; and Fig. 3, a side view with one of the wheels partly broken away, showing a slight modification.

Vehicles of the class referred to have had their springs arranged in a variety of ways, to lessening or overcoming the of the horse; but the construction below set forth is believed to accomplish the desired end more perfectly and cheaply than former plans.

A represents the body or box, which may be of any'usual'or desired pattern; B, the axle,- O, the wheels; D, the shafts; and Ethe main side springs supporting the box upon The box or body rests upon and is straps a, preferablyof metal, resting at their ends upon and bolted or riveted to the upper sides of the elliptic side springs. E, which are in turn mounted upon the axle B, and connected therewith by hinge joints or connections b, which permit a movement of the body and the axle, each independent of the other. The shafts D extend back and are rigidly attached to the axle B, and each shaft bears a spring, F, which extends forwardand connects with one end of a bow-shaped crossspring, G, the middle portion of which may be secured to the under side of the box or body, as shown, or which maybe carried by jack-irons extending forward in advance of the box, as is common in many vehicles.

Under the foregoing construction the weight of the load comes upon the main side springs,

directly over the axle, and the springs E being practically balanced upon the axle, or

upon the hinge-joints b, are prevented by the springs F G from being rocked or tipped out of position. At the same time the springs F G, being comparatively light, and the rigid end of springs F being made fast to the shafts, close to the joints b, it follows that,

although a considerable motion is given to the forward ends of the shafts, the motion is very slightat the points where the springs F are applied, and consequently said springs the motion of the horse is transmitted to the box or body. The hinge-joint might be at the upper side of the spring instead of the lower, but would not give as good results as under the arrangement shown and described.

Instead of bending the shafts and connect- 7 5 ing them directly to the axle, they may be made straight, carried along each side of and secured to the box or body A, as in Fig. 3, the joint or hingeb being in such case omitted,

or braces or stay-rods 0 being provided to prevent the axle from swinging backward, if the joint be used.

The springs F may be applied to the body I and spring G to a cross-bar on the shafts.

I am aware that it is not broadly new to provide a two-wheeled vehicle with side springs connected withthe axle or with the body by pivots, and hence I'do not claim such construction, broadly.

Having thus described my invention, what I 9o claim is- V 1. The herein-described vehicle, consisting of bodyA, axle B, wheels 0, shafts D, con nected to the axle, side springs,E, supporting the body and connected with the hinge-joints, springs F, secured to the shafts,

axle by 5 and cross-spring G, attached to the body, and secured to the fore part of the body, and having its ends connected with the springs F, springs running lengthwise of the shafts and all substantially as shown and described. having their forward ends connected with the 2. In combination with the body and shafts ends of the cross-spring and their rear ends 15 5 of a vehicle, intermediate connecting-springs, attached to the shafts, substantially as shown F G, applied substantially as shownand deand described.
